TFT型的液晶显示器较为复杂，主要的构成包括了，荧光管、导光板、偏光板、滤光板、玻璃基板、配向膜、液晶材料、薄模式晶体管等等。首先液晶显示器必须先利用背光源，也就是荧光灯管投射出光源，这些光源会先经过一个偏光板然后再经过液晶，这时液晶分子的排列方式进而改变穿透液晶的光线角度。然后这些光线接下来还必须经过前方的彩色的滤光膜与另一块偏光板。因此我们只要改变刺激液晶的电压值就可以控制最后出现的光线强度与色彩，并进而能在液晶面板上变化出有不同深浅的颜色组合了。
TFT type liquid crystal display is more complex, the main components include: fluorescent tube, light guide plate, polarizing plate, filter plate, glass substrate, matching film, liquid crystal material, thin mode transistor and so on. First, the LCD must use the back light source, that is, the fluorescent lamp to project the light source. These light sources will first pass through a polarizing plate and then pass through the liquid crystal. At this time, the arrangement of the liquid crystal molecules will change the light angle through the liquid crystal. Then the light must pass through the front color filter and another polarizer. Therefore, we can control the light intensity and color at last by changing the voltage value of the stimulation liquid crystal, and then change the color combination with different depth on the liquid crystal panel.
